Live nodes that have tokens indicating they should receive a copy of data count towards write quorum. This means if a node is down (not decommissioned) the copy sent to the node acting as the hinted handoff replica will not count towards achieving quorum. If a token is moved, it is moved. It is not in 2 places at once. If you are using CL.QUORUM and it succeeds, it really is reading or writing RF / 2 + 1 copies.
